The suit filed Friday in Franklin Circuit Court requests an injunction to block further distribution of the fliers.

Grimes’ campaign says it will ask authorities to investigate whether the fliers circulated in several counties violated Kentucky and federal laws.

The mailer is labeled as an “Election Violation Notice” and warns recipients they’re at risk of “acting on fraudulent information.” It says Grimes has tried to deceive voters in her campaign to unseat Senate Minority Leader Mitch McConnell.

Grimes campaign manager Jonathan Hurst calls it an attempt to keep people away from the polls.
